Proform CRosswalk 325x not working

My treadmill just started to seem to have a slight burning smell after about 15-20 minutes. Then it stopped. Control panel comes on, and incline works. Thought it was the motor and was going to order a new one, as seems to be simple to replace. But then I have read it could be the MCB. If I were to borrow a volt/ohm meter, which is needed to test if, how easy is it to diagnose what the problem might be?

A burning smell coming from the treadmill can really cause some concern and I will be happy to help. I suggest you add to the thread of this question and include the full model number of your treadmill so that the expert can provide you with a more detailed answer. I did manage to find a link with a similar question. I hope this helps with your research while you wait for your expert response.

. I understand how frustrating it is having trouble with your treadmill stopping. We are here to help. I recommend the walking belt tension be checked. If the walking belt is too tight the controller or motor will overheat, shutting the treadmill down. The proper way to adjust the belt is listed on page 14 of the owners manual.

. If the belt is adjust properly and the treadmill still shutting down, unplug the treadmill. Next, remove the black motor control cover. Now, check all the wires on the motor control board. Make sure all the wires are plugged in and tight. To determine which part is bad, plug the treadmill in and run the walking belt with the black cover off. Run the belt for about 10 minutes and shut the treadmill off. Now, check the motor and control board with your hand. The part that is burning hot is bad. Most likely it will be the controller. The motor rarely goes bad. The part number for the controller is 137860. I hope this helps.

Randy, try putting the treadmill in calibration mode. Look for the speed calibration. That may get the belt moving. The image below will help you calibrate the speed. If nothing happens measure for dc voltage to the motor. If there is no voltage to the check the controller. Also ohm out the motor. I provided the link to a treadmill schematic. You may have the exact schematic on the belly pan or attached to the black motor cover. Most likely the controller is bad.
